I fancied one of those Surface One controllers too - spoke to M-Audio here in the UK and it looks like it's definitely not coming out. I reckon at the moment the next best thing for roughly the same money is the Evolution one that's on the Ableton home page at the moment.
I'll tell you what, that Kenton "control freak" is supposed to be OK aswell.
Im selling the a Kenton control freak live edition 16 knobs and buttons for £160. Mint cond. havent got round to putting on ebay yet
